1 Claim.

This invention relates to improvements in smoking pipes.

One of the principal features of the invention resides in a smoking pipe in which the smoke from the bowl is filtered in its passage through the stem to prevent the clogging of the bore of the stern with tobacco bits, and the unpleasant drawing of tobacco bits through the mouthpiece into the mouth of a user.

Another feature of the invention is to provide a smoking pipe in which moisture which may seep into the bore of the stem is trapped in a manner as not to interfere with the draft through the stem.

A further object of the invention is the provision of a smoking pipe for trapping tobacco bits and moisture within the stem of the pipe, and which aiords cleaning of the trapped substances without disturbing the connection between the mouthpiece and pipe stem.

A still further object is to provide a filter attachment which is inserted in the stem of a pipe, or the mouthpiece of a cigarette or cigar holder as a unit and which may remain in position indenitely without removal.

A still further object is the provision of a lter attachment having the above features which is simple of construction, inexpensive of 'manufacture, and which is capable of unlimited life.

With these and other objects in View, theV invention resides in the certain novel features of construction, combination and arrangement of parts, the essential features`of which are hereinafter fully described, are particularlyT pointed out in the appended claim, and are illustrated in the accompanying drawing, in which:

Figure 1 is a vertical longitudinal sectional view through a smoking pipe showing my invention embodied therein.

Figure 2 is an enlarged horizontal sectional view on the line 2-2 of Figure 1.

Figure 3 is a detail perspective view of the lter member per se.

Figure 4 is a fragmentary horizontal sectional View showing a slightly modied form of the invention.

Figure 5 is a vertical sectional View of the form of filter member shown in Figure 4 embodied in-a cigar or cigarette holder.

Figure 6 is a perspective View of a further modied form of lter member per se.

Referring to the drawing by reference characters, and more particularly to Figures l to 3 inelusive, the numeral I0 designates a smokers ar- (o1. lai- 12) ticle in its entirety which is shown in the nature of a smoking pipe which vincludes `a bowlY I I `from which a stem I2 extends, the said stem having a bore I3 lof uniform diameter which communicates with the interior of the bowl I'I at the bottom thereof. Fitted into the outer end'of the bore I3 is the reduced inner end I4 of a mouthpiece I5, the reduced end I4 having an outwardly extending Ytube I6 extending therefrom, and which tube communicates'with the bore I1 in 10 n the mouthpiece I5.

Fitting into the bore I3 and disposed adjacent the point of communication between the interior of the bowl II and the bore, is a lter member I8. The lter member I8 includes a disk-like l5 plug body I9 of a diameter to snugly fit the walls of the bore I3, while the center of the plug member I9 is provided with a passage 20 which is in axial alinement with the bore of a tube 2l extending from the disk I9 and integral therewith 20 and which is disposed in spaced relation to the Y walls of the bore I3 and which terminates short of the outer end of the tube I6.

The face of the disk I3 opposite that from which the tube 2l extends, is provided with radial 25 slots 22 which extend from the opening 2G outwardly to the periphery of the disk I9. The modied form of the invention shown in Figure 6 includes the construction so far described, and like reference characters refer to similar parts 30 Whereas in Figures l to 3 inclusive, the lter unit includes a pair of outwardly extending guard members 23. Each member 23 is of barb shape and the same are disposed in close proximity and parallel toreach other so that in side elevation, 35 they coact to provide a substantially arrow head extension. The guard members 23 are so positioned With respect to the narrow slots 22 thatV they are disposed out of the plane Vof the slots and out of the plane of the opening 29 so as not 40 to interfere with 'the passage of smoke through the slots and into the passage 20.

By reference to Figures 1 and 2, it will be seen that the guard members 23 extend Within the bowl II adjacent the bottom thereof and 45 serve to prevent excessive packing of tobacco against the disk I9 to avoid clogging up of the slots 22 and opening 20.

The bore I3 between the disk I9 and the reduced end I4 of the mouth piece I5 constitutes 50 a trap for the accumulation of moisture which may drain inwardly from the mouth piece I5 and collect any tobacco bits which might accidentally seep through the filter device I8. For the purpose 0f draining the bore I3 of any moisture 55 which might accumulate therein, the bottom of the stem I2 is provided with a drain opening 24, the walls of which threadedly receive a screw plug 25.

For the purpose of inserting the filter member I8 into the bore I3 before the attachment of the mouthpiece I to the stem., it may be necessary to employ an instrument in the form of a Spanner and I therefore provide kerfs 26 in the outer side of the disk I9 for that purpose.

From the foregoing description, it willjbe seen that when the smoking pipe is in use, smoke may be drawn from the bowl II through they, narrow slots 22 and passage 20 in the disk I9 and thence through the tube 2I into the enlargedy bore I3, and thence outwardly through the tube I6 and Abore I'I in the mouthpiece.

In Figure 4 of the drawingl a slightly modified form of my invention has been shown in which the inner end of the bore I3 is screwathreaded as at 21 for threadedly receiving a threaded periphery 28 of the disk I9 of the filter device. For facilitating the screwing of the disk I9 `into position,v the outer end of the tube 2I is provided with kerfs 26 for the reception of a screw driver or otherklike instrument.

In Figure 5 of the drawing,'the same construction of lter device as is shown in Figure 4 is illustrated but is shown in use in connection with a cigarette or cigar holder 29 which includes a stem I2', a mouthpiece I5 fitting into onefend of the stem I 2',-a tube I6 extending inwardly from the mouthpiece I5' in spaced relation to the walls of the bore I3 of the stem. The outer socket 30.

. aos'aieseV free end of the stem I2 is provided with a socket 30 for thel reception of one end of a cigarette or cigar 3| and the barb shaped guard members 23 of the filter device I8 extend into the socket 30 and provide an anchorage for the inner end of the cigar or cigarette when placed in the holder 29. The disk I9 of the filter deviceris threaded to an internally screw threaded portion 21' provided in the stem I2 jlust inwardly of the The filter device shown in Figure 5 operates in the same manner as that shown in the lpreceding form, with the exception that the prising a disk having a central opening `therein adapted to be fitted into the bore of a pipe stem, cigar holder, or cigarette holder, and slots provided in the outer face of said disk and extending radially' from said opening, a pair of spaced alined reversely arranged barbs extending from the slotted face of said disk but disposed out of the plane of said slots.
